An effective diastereoselective [3 + 3] cycloaddition of 1,4-dithiane-2,5-diol with azomethine imines catalyzed by DABCO is described. A variety of highly functionalized six-membered dinitrogen-fused heterocycles can be obtained in good yield with excellent diastereoselectivity, which was controlled by anomeric effect.

Based on general SARs previously described for anti-HIV-1 diarylsulfone derivatives, a series of 2-amino- and 2-carboxamido-3-arylsulfonylthiophenes has been prepared and evaluated as potential antiviral and antitumor agents. In cell culture, some of the 2-aminothiophenes exhibited moderate and selective activity against...

A bifunctional squaramide catalyzed sulfa-Michael/aldol cascade reaction between 1,4-dithiane-2,5-diol and chalcones with a low catalyst loading has been developed. Trisubstituted tetrahydrothiophenes with three contiguous stereogenic centers are obtained in a highly stereocontrolled manner. Additionally, a remarkable temperature effect on reaction...

2,5-Dihydroxy-1,4-dithiane (I) and its derivatives (II-IV) showed rather marked inhibitory activities on the growth of the roots of two plant species. All compounds tested had phytogrowth-inhibitory activities. These compounds markedly inhibited the growth of the two plant species at the...
